Doors Fail To Lock From One Switch

Lower both front door windows. Turn ignition off and close all doors. Lock and unlock doors from all door lock switches, including door lock key cylinder switches (if equipped with VTSS). Observe door locks. If all doors fail to lock from one switch, replace suspect door lock switch. If symptom is different, go to another symptom test that matches malfunction description.
